我该怎么做才能显示所有event_group_members具有相同的eg_id user_id
1 1

答案 0 :(得分：1)
试试这个：
foreach($members as $member)
{
echo $member->id;
// It will echo diff id for each iteration
}
说明：$ member是一个具有多个值的Std类对象，如果您使用它：
$members[0]->user_id;
表示您正在引用其第0个索引值。要访问所有值，您必须使用循环。
答案 1 :(得分：0)
你可以这样做
public function getGroupInfo($eg_id){
$userNames = array();
$members = \App\EventGroupMembers::where('eg_id', '=', $eg_id)->get();
if ($members->count() > 0) {
foreach($members as $data){
$user = \App\User::where('user_id',$data->user_id)->get();
foreach($user as $userData){
$userNames[] = $userData->first_name;
}
}
} else {
return false;
}
}
然后您可以从该阵列中检索用户名。
foreach($userNames as $name){
echo $name;
}
答案 2 :(得分：0)
您在user_id模型中有EventGroupMembers，因此您似乎正在使用已在EventGroupMembers和User模型之间{{}}}的应用。因此，请在event_group_members模型中的User表格迁移和关系中查看one-to-many relationship。
public function eventGroupMembers()
{
return $this->belongsTo('App\User');
}
之后，您可以按eg_id型号中的EventGroupMembers过滤用户：
$members = User::with(['eventGroupMembers' => function($q) use ($eg_id) {
$q->where('eg_id', $eg_id);
})->get();
此解决方案只对数据库执行两次查询。
然后只列出用户＆＃39;刀片模板中的名字：
@foreach ($members)
$member->first_name;
@endforeach
